METHOD OF WEAVING PILE FABRICS.

SPECIFICATION forming part of Letters Patent No. 695,582, dated March 18, 1902.

Application filed December 26, 1899.

useful Improvements in the Method ofWeaving Pile Fabrics, of which .the following is a My invention has relation to improvements in the art or method of manufacturing terry pile fabrics of that type wherein two separate fabrics are woven face to face to form two dis-' tinct webs.

The new method consists in introducing the loop-Wires simultaneously with the shoots of filling, whereas in the former methods the filling and loop wires were led in one after the other.

In the accompanying drawings, Figure 1 is a sectional side viewof a terry pile fabric, showing the pile-warp threads lowered when introducinga wire into the upper fabric. Fig. 2 is a somewhat similar view showing the lifting of the pile-warp threads when the wire for the lower fabric is being introduced, and Fig. 3 is a similar view showing the insertion of a weft to bind the pile-warp of the upper fabric over the pile-wire.

Similar letters of reference indicate corresponding parts. I V

a b, respectively, indicate the pile-warps for the upper and lower fabrics, and c indicates the filling or weft. (1 indicates the body or ground warp.

e indicates the upper and lower bindingwarps. r

1' indicates the loop wires or rods which are used in producing terry pile fabrics.

In my improved method of producing terry pile fabrics the pile-warp a for the upper fabric is lowered by the heddles, so that the wire 1' may be introduced over the same, and simultaneously with the introduction ofthe said wire a shoot of the filling c is passed into the lower fabric, as shown in Fig. 1, after which the said pile-warp a is raised, and, as shown in Fig. 2, the pile-warp b of the lower Serial No. 741,620. on specimens.)

fabric is also raised, during which position the wire r for the lower fabric is introduced I direction simultaneously with the raising and lowering of the pile-warps a and b to permit the insertion of a weft c. When a wire has been introduced, as shown in Figs. 1 and 2,

the next shifting of the pile-warp threads by the heddles is accompaniedby a shoot of filling or weft into the upperffabric, as shown in Fig. 3, so that the loops are formed and the wire bound in position.

Through the medium of the described method-the time required for the. introduction of the rods is shortened and a'greater working capacity of the loom is produced. The manner of operating the 100m is also through the new method simplified and improved. v

- I have shown a combined cut and terry plain pile fabric, and when forming the plain or cut pile the pile-warps of either the upper or lower fabric are caused to extend from the upper to the lower fabric and be bound into the body or ground, and in weaving the cutpile portion I do not employ the loop-wires; but the pile warp is afterward severed through the center, and thus a plain cut-pile fabric is pr0duced.

What I claim'as new is- The ethod of making terry pile fabrics face to face, which consists in raising and lowering the pile-warp threads of each fabric alternately, and introducing the loop-wires simultaneously with the shoot of filling in the opposite fabrics.-

In testimony thatI claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses. v

HEINRICH ROSGEN.
